我第一次尝试学习CakePHP(我通常只学习纯代码PHP),我从他们主持的“官方”博客教程开始:http://book.cakephp.org/1.3/en/The-Manual/Tutorials-Examples/Blog.html
到目前为止,我已经安装了一个虚拟主机(在OS X 10.8.2上),并使用CakePHP的默认索引页来确保它正确地从数据库中读取,应用/tmp文件夹可递归写入Apache等。
在设置了初始博文视图之后,当我尝试关注博文时遇到了问题,它说您现在可以在(将“www.example.com”调整为我的本地服务器名)“cakeblog/Posts/index”上查看博文。我很确定我有一些修改的问题,但我不知道是什么。无论何时发生这种情况,我的Apache错误日志如下:
[Thu Feb 14 09:18:10 2013] [error] [client 127.0.0.1] File does not exist: /Users/bailey/Sites/cakeblog/posts
[Thu Feb 14 09:18:10 2013] [error] [client 127.0.0.1] File does not exist: /Users/bailey/Sites/cakeblog/favicon.ico
我知道favicon存在于我的webroot文件夹中,位于/Users/bailey/Sites/cascade/extranet-cake/app/webroot。如果我理解路由权,那么cakeblog/posts/index应该是PostsController的控制器,/index应该是PostsController“index()”中的操作/方法。所以它似乎不认识控制器?
我在博客教程中设置的代码是:
(app/Model/Post.php):
<?php
/*
Model: represents a data model (object).
Examples -> a blog, a post, a comment on a post
*/
class Post extends AppModel
{
}
?>
(app/Controller/PostsController.php):
<?php
/*
Plays with Posts Model and gets work done.
- function "foo()" means that the function is accessed by
going to DOMAIN/posts/foo
*/
class PostsController extends AppController
{
public $helpers = array('Html', 'Form');
// An action!
// www.example.com/posts/index => listing of all posts
/*
Sets the view variable called ‘posts’ equal to the return
value of the find('all') method of the Post model.
*/
public function index()
{
$this->set('posts', $this->Post->find('all'));
}
}
?>
(app/查看/帖子/index.ctp):
<!-- /app/View/Posts/index.ctp -->
<h2> Blog Posts </h2>
<table>
<tr>
<th> ID </th>
<th> Title </th>
<th> Date Created </th>
</tr>
<!-- Output the actual posts -->
<?php
foreach ($posts as $post)
{
/* Data ~ $post[ModelName][VariableName] */
$id = $post['Post']['id'];
/*
"$this->Html" ~ a Helper
link() generates an HTML link with given title and URL
*/
$titleLink =
$this->Html->link($post['Post']['title'],
array('controller' => 'posts', 'action' => 'view', $post['Post']['id']));
$dateCreated = $post['Post']['created'];
$out = "<tr>
<td>$id</td>
<td>
$titleLink
</td>
<td>$dateCreated</td>
</tr>";
echo $out;
}
unset($post);
?>
</table>
这是我第一次真正了解CakePHP,我在其他任何帖子中都找不到解决方案,除了怀疑mod_重写问题的间接原因。有人知道我遗漏了什么吗?我可以发布我的httpd。conf文件,也可以根据请求。
[已解决]
愚蠢的错误——原来我使用了app/webroot以外的子文件夹作为webroot。一旦我改变了这个,它工作得很好。
如果我想使用一个不同于默认的webroot,一个替代方案是由杰里米哈里斯在上面的评论中给出的,并在CakePHP文档中得到支持:

谢谢大家的帮助!
